N. Y., a corporation of New York I Application December 4, 1945, SerialNo. 632,619

This invention relates to journal box lid structures.

An objectof the invention is toprovide a journal box structure-of theopen face typehaving a lid construction employing a hairpin type torsionspring having two coiled portions bearing on the lid, ayokeextendingupwardly from the coiled portions bearing on the cam lug ofthe box and arms extending upwardly from the coiled portions bearing onthe hood or carrier between the coiled portions and the lug.

A further object. is toprovide a journal box structure as aforesaidwherein the bearing of the spring arms on the carriris in the nature ofa fulcrum leaving the spring free to assume the desired position. forits engagement withthe. lid, lug and carrier.v H

A further object is to'provide ajournal box structure as aforesaid.wherein .a sturdy articulated joint is provided for firmly connectingthe lid to the carrier while permitting a tilting movement of the lidabout transverse and longitudinal axes relative to the carrier.-

Other and further objects of the invention will appear from thefollowing description, the accompanying drawings and the appendedclaims.

Referring to the drawings forming a part" of this. application, Figurelis a front elevation of a journal box structure embodying the presentinvention, the journal boxbeing indicated in dot and dash lines; Fig. 2is a section on the line 11-11 of Fig. 1, parts being shown in full andthe journal box being shown fragmentally in dotand dash lines; Fig. 3 isa section on the line III-III of Fig. 1, parts being shown in full andthe journal box being shown fragmentally in dot and dash lines; Fig. 4is a view similar to that of Fig. 1

(Cl. 30847) an open face 2 and anorificed cam lug 3 above the open face. A lid 4 closes the open face 2and is of the usual eyeless type having a four-sided rearwardlyextending rib 5, a peripheral rearwardly extending flange B overlappingthe walls of the box when the lid is closed, 2. depending orificedtongue 1 to facilitate opening and closing the lid and spaced upwardlyextending lips 8. The lid preferably, but not necessarily, is providedwith a rearwardly extending recess 9 for a purpose later to appear.

A hood or carrier l0 supports the lid. It has a front Wall ll, sidewalls l2, 3. top wall l3 and a bottom wall I l. The side Walls l2 haveupper rearwardly extending orificed ears 15, the orifices of which arein line with the orifice of the lug 3. A hinge pin [6 extends throughthe ear and lug orifices thereby pivotally mounting the carrier upon thelug. The pin may be of any suitable type. It is shown as having a head Hat one end and its opposite end is split, providing branches l8, one ofwhich bent to retain the pin in place. I The lid is connected to thecarrier by an articulated joint IS. The lips 8 are disposed one adjacenteach of the side walls 12 serving to prevent any tendency of the lid toturn in its plane relative to the carrier. The side walls l2 at theirrear edges 20 opposite the lid are somewhat spaced therefrom leaving thelid free to firmly seat upon the edges of the walls of the box adjacentthe open face 2. The space allows a free limited tilting movement of thelid relative to the carrier when the lid is raised and lowered torespectively open and close the box, thismovement being checked by theedges 20 engaging the lid.

A plate 21 is secured at its upper end by rivets 22 to the lid 4 at itstransverse central portion. The lower end of the plate is shaped to forma forwardly extending loop 23 which provides part of the articulatedjoint IS. The loop may be closed but it is preferably, as shown, open atthe side adjacent the lid 4. A transverse bar 24 forms the other part ofthe articulated joint !9. The bar 24 has a center portion circular incross section and the loop 23 is mounted on this portion of the bar. Thebar 24 is mounted in orifices in the side walls [2. The bar is providedat one end with a head 25 and is secured at its other end to theadjacent sidewall l2 by weld metal 26.

A hairpin type torsion spring 2'! is housed in the carrier. It is formedof two spaced coiled portions 23, one adjacent each side wall It. The

suitable gauge to render the required force and the coils of the coiledportions are large in di am ter to aid in providing the requiredflexibil ity to insure the lid firmly seating upon the box. The springat the rear portion of the inner coil 29 or" each coiled portion (i. e.its portion adjacent being the axis of the bar 24.

the lid =3), extends upwardly to form a yolge :50,

the upper end of which has a roller fil mounted thereon which engagesthe cam face of earn ing The spring at the forward portion of theoutercoil 32 of each coiled portion (i. re. its portion adjacent thewall I 5), extends upwardly to form. an;

arm. 33.

The arms 33 have outwardly bent upper ends it and the wall H hasorifices 35 through which the bent ends at extend. Beneath the orifices35 the wall 5 l is depressed rearwarclly opposite each arm 33. Thesedepressions are disposed between the coiled portions 28 and'the roller3i and engage the arms 33 providing thereby fulcrums defer V the spring.The energized torsion spring produces simultaneous spring pressures uponthe lid, the pa n lug, and upon the fulcrums. The i mm a l t te he sprng assumi he sp pressed engagements. i l

The coiled portions of the spring engagethe central portion of the lid to p ovid the de bl ocation of e re sur uo the lid, and consequently the articulated joint is will be disposedsubstantially opposite the central portion of the lid.

7 Where the recess 9 is employed this Will likewise be at the centralportion of the lid, and the coiled portions of the springs will seat inthe re,- cess. The recess to this end is a cuate in c oss section and ofa radius substantially equal to the outer radius of the spring coils.The recess 9 does not lessen the ability of the lid to tilt as aforeesaid. It has the advantage of providing more t et e n the l d and ar-mere a a lar er I a so af d spring coil may be employed, added support forthe spring and m y be in some cases relied upon. for total support ofthe spring where it is desired to eliminate the 'bent en ds 34 u h i ispr able that h se b n ends be mp d a he definitely osition the a ms 33.W i a s n r c 9 has b n emp o ed, it Will e un er d hat two may be e p oed. one for each of the coiled portions.

The lid is supported by the carrier through the u p r p rt n at of thnerface of the loop 23 n ing th corre ponding upper portion 32;. of thebar 2:3, and this engagement should be along hap d simi r y totheoverthe projection.

- upper end tilting of the lid about a transverse axis, this axis Thespring produces a force tending to spread the lid and carrier apart andthis is resisted by p the engagement of the portion 39 of the inner faceof the loop with the corresponding side portion it of the bar which isopposite to but remote from the lid l. These engaging faces provide forthe tilting of the lid about a longitudinal central vertical axis. Thisengagement should preferably be substantially line contact. To this endiheport n 3% 0f e 9915 c rved a shown in Fig. 3 providing line contactwith the portion 49.

The sidewalls I2 have aligned orifices 41 and the yoke 38 is curvedsomewhat forwardly to partly intercept the path between the orifices.

' Wien the yoice is forced forwardly to escape this path a pin (notshown) may be inserted in the orif ces to hold the roller in thisposition. This a usual expediency followed in assembling the lidconstruction with the box or removing it therethat similar]constructions are employed for each as n of the spring. Furthermore ineach instance only portion of an arm and a portion of the front wall ofthe carrier are shown.

In Fig. Qthe carrier Inc is provided at its front wall with a forwar'dlycurved vertical, socket $2 for the arm 33a. "Thearm ssa'has an upper endits curved forwardly similar to the socket 42, which seats inthesocketA}; 'j

The spring arm isspringpressed against the carrier at the joint therebee n- J in is fe aby d sp ed at a location on the earrier'front wall similar to thelocation of the fulcrum 36 on the carrier ll) of Fig. 2, namely ate.location between the coiled portions of the spring-and the cam log ofthe box.

Figs; 4 to 6 show an embodiment of the invention quite similar to thatof Figs. 1 to 3 and like parts will 'be'lndioated by like referencenumetals with an accent added. No detailed description is thereforeconsidered necessary and only the points of difference will-be pointedout.

The plate 2! is riveted to the front wall ll of the carrier Ill byrivets 2'2 the loop 23' thereby extending rearwardly. The bar. 24' hasflat ends 52 and these are secured to the lid. 4 by rivets 53. Thus theloop 23' supports the lid 4'. The loop 23 and bar 24' have portionssimilar to; and for the same purpose as, the portions 31 and 38 of theloop and bar resp'ectivelylof Fig.2, but these portions arev at thebottom of the loop and bar-and are indicated respectively by thereference numerals 31 and .38; l

' Likewise the loop ZSand bar 24. have portions similar to, and for thesame purpose as, the portions 39 and 40 of the loop and bar respectivelyof Fig. 2 but these portionsare. at the, opposite side .ofthebar,,i;.e., the side adjacent the. lid 6, and are indicatedrespectivelybythereference numerals 39Kand40f'. V The lid 4, isshow'n ashavingthe recess 9', and where this .recess is employed thefiat ends ofthe bar I 24; are preferably formed, withstheir rear faces. 54 flushwith the rear face of the bar 2.4 thereby providing a space between thebar and recess into which the loop 23'. extends'as shown in Fig; 6. Theiiatends 52 arepreferably rectangular'in cross section and thewalls I!are cut out to provide slots 55ffitting these fiat ends but with enoughclearance to permit the required tilting of the lid 4.

Figs. '7, and 8/ show an jembodimeint of the invention quite similar tothat of Figs. 4 tot,

and like parts will be indicated by like reference numerals with twoaccents added. No detailed description is therefore considered necessaryand onlythe points of difference will be pointed out.

The loop 23" ismore U,-shaped;than the loops of the other twoembodiments, having a' bottom leg 55, a top leg 51, and'a ourvedbend 58.The

bar. 24" is formed from a fiathstrip of metal having fiat'ends 59secured to the lid 4" by rivets 60; The bar between the hat ends isbent; to form a U-portion 5i open forwardlyand has a bottom leg 62, atop leg 63, and a curved bend B4.

The curved bend 58 has a curved portion 39" similar to, and for the samepurpose as, the

curved portion 39' of the embodiment of Figs.

4 to 6. The curved bend 64 seats on this portion 39 to provide similarline contact to permit tilting or angling of the lid 4 ,about alongitudinal central axis relative to the carrier 13'}.

The leg G'Z seats uponthe leg fifi overfabroad area providing amplesupport forthelid 4' by the carrier and minimizing thewear betweentheengaging faces of the legs Stand 62;. "The legs and 63 divergesomewhatiforwardlyjto provide suificient clearance necessary to allowfor L the desired tilting of the lid 4" about atransverse centralaxisrelative to. the carrier i0".

While in the embodiment shownin Figs. 7- and 8 the plate?! isrriveted tothe carrier ifif and the bar 24 is riveted tovthe lid 47 they may bereversed and, similar to Figs. 1 to 3, the plate 2! may be riveted tothe lid 4'. andthe bar 24" may be riveted to the carrier in. In such'aconstruction, as is obvious, the, loop 23C.

and the bar 24" will be reversed in direction. The bar will then supportthe lid 4" and the U-portion 6| must be sufficiently spaced from theWall E I" to provide room for the loop 23f. Furthermore theleg 53 willsupportingly engage the leg 51 and the legs 56 and 62 will be spacedsimilarto the space between the legs53 and 5lzoi.Fi 8.

'While there have been hereinbefore described approved embodiment ofthis invention, it will be understood that many and various changes andmodifications in form, arrangement of parts and details of constructionmay be made thereto without departing from thespi'rit of the invention,andthat all such changes and modifications as fall within the scope ofthe appended claims are contemplated as a part of this invention.
